Adata set contains an independent and dependent variable. which must be true of the data set if a linear function can be used to represent the data? the set must have a constant additive rate of change. the set must have a constant multiplicative rate of change. the values in the set must be positive. the values in the set must be increasing.

The correct answer would be A.) The set must have a constant additive rate of change. I just took the test

Step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

is there supposed to be a diagram or a graph for this one? ?
